Owen Grady and Astrid Hofferson
"Usually," Astrid said. She wasn't stupid enough to think that Stormfly was a harmless creature. She wasn't. She could kill someone easily if she wanted to. But Astrid didn't believe she wanted to. But if she was angry, or frightened, or someone was threatening Astrid...well, she was less than safe and she didn't want to lie to this guy about that.
"But you have to be careful around dragons. Underestimating them is a good way to get yourself hurt."
She smiled and seemed to relax a little at his last words.
"My betrothed does that. He trains dragons. He's the best at it."
